4. Reinstall the oil fill cap/dipstick and tighten
securely.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with the oil level below the ‘‘L’’
mark or over the ‘‘F’’ mark on the dipstick.
Change Oil Filter
Replace the oil filter every other oil change (every
200 hours of operation). Always use a genuine
Kohler oil filter.
Replace the oil filter as follows:
1. Drain the oil from the engine crankcase.
2. Remove the oil filter drain plug (where applicable)
located at the base of the oil filter adapter. Allow
the oil filter to drain.
3. Remove the old filter and wipe off the filter
adapter. Reinstall the oil filter drain plug. Torque
the drain plug to 7.3-9.0 N·m (65-80 in. lb.).
4. Place a new replacement filter in a shallow pan
with the open end up. Pour new oil, of the proper
type, in through the threaded center hole. Stop
pouring when the oil reaches the bottom of the
threads. Allow a minute or two for the oil to be
absorbed by the filter material.
5. Put a drop of oil on your fingertip and wipe it on
the rubber gasket.
6. Install the replacement oil filter to the filter
adapter. Turn the oil filter clockwise until the
rubber gasket contacts the filter adapter, then
tighten the filter an additional 2/3 to 1 turn.
7. Fill the crankcase with new oil, of the proper type,
to the "F" mark on the dipstick.
8. Test run the engine to check for leaks. Stop the
engine, allow a minute for the oil to drain down,
and recheck the level on the dipstick. Add more
oil, as necessary, so the oil level is up to but not
over the "F" mark on the dipstick.
Full-Pressure Lubrication System
Operation
This engine uses a full-pressure lubrication system.
This system delivers oil, under pressure, to the
crankshaft, camshaft, balance shaft, and connecting
rod bearing surfaces. In addition to lubricating the
bearing surfaces, the lubrication system feeds oil to
the hydraulic valve lifters.
A high efficiency Gerotor ™ oil pump is located in the oil
pan and is driven by the balance shaft. A pressure
relief valve in the oil pan limits the maximum pressure
of the system.
Service
The oil pump rotors can be serviced without removing
the oil pan. Remove the oil pump cover on the PTO
side of oil pan to service the rotors.
The oil pan must be removed to service the oil pickup
and oil pressure relief valve.
See Figures 6-6 through 6-8. Also refer to the
‘‘Disassembly’’ and ‘‘Reassembly’’ sections for
lubrication system components removal and
installation procedures.
